On a rainy night, hiding behind a pushcart food stall parked in front of a dizzyingly lit mall, Raju is busy at work. This timid 10-year-old works 12-hour days serving customers and scrubbing mountains of utensils with tiny hands that appear callused by detergent.

After a full day, he often pockets less than a dollar. If there's food left over, he gets a meal. If not, he goes home on an empty stomach.

Concerned about the future of children like Raju, India Tuesday begins implementing a country-wide ban on children below 14 working as domestic help or in the hospitality sector. And punishment for those who choose to defy it is stringent: imprisonment for up to two years and a fine as high as $430.

Children in India are already banned from working in factories, mines, and other perilous jobs. India's Child Labor Act, first passed in 1986, will now carry two more in a list of 57 professions deemed "hazardous" for children.

Child rights activists in India say it's an important step in the battle to stop child labor. But some worry that the government is still not doing enough to provide alternative options for families that depend on income from their children. And many are skeptical about how effective enforcement of the ban will be.

"It is important to remember that the problem won't disappear by just introducing a ban," says Shireen Miller, head of policy at the India branch of the US-based Save the Children organization. "Legislation is a start," she says pointing out that previous legislation hasn't been stringently enforced.

"Now there's a clear signal that [no one] can get away with employing and exploiting children as workers," says Shantha Sinha, an anti-child labor activist who in 2003 won the prestigious Ramon Magsaysay Award. Ms. Sinha recalls how all 34 cases of domestic child labor that she took up last year – most of them of children brutally beaten by their employers – couldn't stand up in court. All of the accused wriggled out of blame, she says, as employing children as domestic help wasn't then prohibited by law. She hopes this ban will reverse such tendencies.

India has the largest number of child laborers on the planet. And studies by non-governmental organizations (NGOs) reveal shockingly high levels of emotional, physical, and sexual abuse among children working as domestic helpers.

According to the New Delhi-based, National Sample Survey Organisation, nearly 16.4 million Indian children aged 5-14 years are engaged in economic activities and domestic or non-remunerative work. The World Bank puts that figure at 44 million.

NGOs are demanding the purview of such a ban be extended to include all children below the age of 18. Research by Save the Children shows that 74 percent of child domestic workers in India are between the ages of 12 and 16.

"This amendment leaves a large chunk of child domestic workers out in the cold," says Ms. Miller.

Ingrid Srinath, the CEO of Child Rights and You (CRY), a New Delhi based NGO, calls the ban notification "insular" and is skeptical that it will do much good in its current form.

The ban, he says, does little to address the reasons that compel children to work: backbreaking poverty, family debts, marginalization, and migration of their parents.

A recent study conducted by the International Labour Organization found that "children's work was considered essential to maintaining the economic level of households, either in the form of work for wages, of help in household enterprises, or of household chores in order to free adult household members for economic activity elsewhere."

Raju's father, a daily wage laborer, frets that the ban will only exacerbate his family's financial woes. "At least now, he doesn't steal. He earns his meals with dignity," he says. "If the ban is enforced, he might be forced to beg for alms, or the family might go hungry."

India's Ministry of Labor and Employment hasn't yet spelled out any coherent rehabilitation and education plan for children who they lose their jobs. The Ministry assures that a blueprint to ensure self-sufficiency for the kids will emerge soon.

Activists also say that the ban won't work unless mindsets change. Children are widely employed in the homes of India's affluent and middle classes.

Raju's employer, a coarse, burly man who calls himself Pappu, employs two other kids, 12 and 14. Pappu intends to retain his young employees despite the ban. And if cops pester him, he unabashedly says, he'll do what many Indians often do to give the law a slip – offer a bribe.

He says he doesn't see anything wrong in employing the children. "I give the best I can offer," he says. "I do take care of them. I give them food. The kids won't survive if they don't work."

This notion of benevolence often masks the exploitation and the long-term harm for children, says Ms. Sinha. "Just because children are given food or money doesn't mean that they're benefiting," she says. "They're cheap and work long hours without any question. That's exploitation. The ban now gives weight when we say: 'That's wrong!' "
